With prices for the Folio Silmarillion & Hobbit rarely exceeding £200 (you could reasonably expect to pick up both for less than £300), I think you pick up all three individually for less than £1000; maybe £700-800. They wouldn't be matching numbers though, & this auction also had free postage I suppose.

Out of interest, if they weren't matching numbers, would you guys still think £1000 was good?
